The invention belongs to the technical field of hybrid vehicles and power batteries, and particularly relates to a power battery self-heating method and system, a vehicle and a computer readable storage medium. The power battery self-heating method comprises the following steps: responding to a heating request; vehicle state information is obtained, corresponding self-heating mode information is matched according to the vehicle state information, the vehicle state information comprises gear information, engine working information and whole vehicle fault information, and the self-heating mode information comprises idling self-heating mode information and driving self-heating mode information; response is executed according to the self-heating mode information, and the power battery is controlled to be charged and discharged repeatedly to achieve self-heating of the power battery. Therefore, the self-heating of the power battery can be realized by controlling the power battery to be repeatedly charged and discharged within the preset electric quantity range by virtue of the existing system architecture of the hybrid electric vehicle. The vehicle cost is reduced, better heating temperature uniformity is achieved, and the user experience is improved.

    本发明属于混动汽车及动力电池技术领域,特别是涉及一种动力电池自加热方法、系统、汽车和计算机可读存储介质。其中,动力电池自加热方法包括如下步骤:响应于加热请求;获取车辆状态信息,根据车辆状态信息匹配对应的自加热模式信息,车辆状态信息包括档位信息、发动机工作信息、整车故障信息,自加热模式信息包括怠速自加热模式信息、行车自加热模式信息;根据自加热模式信息执行响应,控制动力电池反复充放电以实现动力电池自加热。因此,本发明能够依靠混动汽车的现有系统架构,控制动力电池在预设电量范围内反复充放电以实现动力电池的自加热。降低车辆成本,实现更好的加热均温性,提升用户体验。
